sd.default

<code>sd</code> computes the standard deviation of the values in x. If na.rm is TRUE then missing values are removed before computation proceeds.

Input/Output, processing and visualization of spectra taken with different spectrometers, including SVC (Spectra Vista), ASD and PSR (Spectral Evolution). Implements an S3 class spectra that other packages can build on. Provides methods to access, plot, manipulate, splice sensor overlap, vector normalize and smooth spectra.
